Allow to disable Stacktrace support

Browse source 
Enable backtrace stuff only if GNU C library used, because current
backtrace implementation based  on  <execinfo.h> , which is not a
part of standard C library, it is a GNU extension.

This will be usefull when building  with  custom POSIX-compilant C
library (like musl) and no <execinfo.h> available.

Note: configure script will detect presence of  <execinfo.h>  and
enable/disable feature depending on it.

Feature is enabled by default.
